Stocking help for new tang setup

[cich-boi]

My tank is 6'x1.5'x2.5' tall.
Currently i have 10 Cypricromis Utinta about 1.5" each

Here is the list of the other fish I'm planning to add:

2 -Gold Head Compressiceps - 1.5 inch
2 -Yellow Calvus - 1 inch
4 - Optalmotilapa Ventralis kambwimba - 1.5 inch
5 - Cypricromis Kigoma - 1.25 inch
4 - Telmatochromis temporalis- 1.5 to 2 inch

My concerns are :-

1. Will the tank size be sufficient for all these ?

2. Is telmatochromis a good mix with these guys. Will it's male be able to color up or it will be bullied ?

3. Can I keep 2 varieties of Cypricromis together ?

2. Is Optalmotilapa Ventralis kambwimba a good mix with these guys. Will it's male be able to color up or it will be bullied ?
